A source close to Drew reveals, “She wants to marry Will fast. Not just because she’s pregnant but because she loves him and wants to be married before the baby is born. Drew’s checking out dresses that will fit her then.”

This will be the third trip down the aisle for Barrymore, who was previously married to comedian Tom Green and British bar owner Jeremy Thomas.

Drew admits she enjoys the “stability” of her relationship with Will, saying, “It’s just the best! We go on group trips and spend holidays together – there’s a lot of love! And that is really nice and very different from the way I grew up, which was more unstable and inconsistent, with a lot of highs and lows.”

Barrymore adds, “It’s funny, when I was younger, I used to say I’d hate a flat line – that I want the ups and downs, the roller coaster. But I’m actually really enjoying the flat line.”
